Hi! I have a system of 13 differential equations that represents a pharmacokinetics in 13 different organs (compartiments) and I want to fit them with my experimental data, however I only have experimental concentrations at different times for two organs. I want to learn how to use isqcurvefit when Function value and YDATA sizes are not equal. Is that possible?
Thanks in advance

Only select the simulated values for the two organs at the times where you have experimental Ydata in the process of parameter estimation.

Thank you very much Torsten!, It works!. It took me a few days to understand what you were referring to because I am actually very new to this. But finally I got it and it works, thank you very much. Your recommendation made me look for how to call the variables and I managed to put together what I wanted.
